I've got a Sempron 3100+ on a Asus K8V SE Deluxe with BIOS rev 1004 (latest currently).I'd like to use the Cool'n'Quiet feature, but the Asus software for Cool'n'Quiet fails under Windows 2000 SP4 on my setup. I think it has problems parsing some files upon initialization. A lot of error dialogs appear endlessly with the same useless message...

Make sure Cool'n'Quiet is enabled in BIOS and also make sure you set your power-scheme to 'Minimal Power Management' in Control Panel->Power Options.

Uninstall the Asus-software and download and install the appropriate Cool'n'Quiet Software from AMD - you can get it here' ">http://www.amd.com/us-en/asset...-64_CPU_driver_W2k.exe

If you like, you can download and run AMD's Cool'n'Quiet/PowerNOW! Dashboard' ">http://www.amd.com/us-en/asset...NowDashboard_setup.zip - it's a small program that will allow you to see Cool'n'Quiet 'at work'.

Just launch the dashboard-utility and then run something CPU-intensive like a Prime95 'Torture test' for example to watch your processor switch to full speed and voltage
